One of the challenging issues in quantum dot sensitized solar cells (QDSCs) is to develop robust and green counter electrodes (CEs) that can replace the transition metal chalcogenides which frequently poison the photoanode during device operation. Herein, electrochemically active graphitic porous carbon (GPC), synthesized on a large scale from human hair bio-waste was successfully applied as a highly...
Since controlled delivery of drug molecules to targeted sites are essential criteria for effective drug delivery, herein a porous nanocarrier chemically functionalized with the drug molecules is developed to accomplish this goal. ∼150 nm diameter porous carbon nanospheres were produced on a large scale from abundant lemon grass (Cymbopogon flexuosus) via silica etching and ball milling followed by...
